A fast algorithm for sparse matrix computations related to inversion
We have developed a fast algorithm for computing certain entries of the inverse of a sparse matrix. Such computations are critical to many applications, such as the calculation of nonequilibrium Green’s functions G and G for nano-devices. The FIND (Fast Inverse using Nested Dissection) algorithm is optimal in the big-O sense. However, in practice, FIND suffers from two problems due to the width...
متن کاملFast Sparse Selected Inversion 1285
We propose a fast structured selected inversion method for extracting the diagonal blocks of the inverse of a sparse symmetric matrix A, using the multifrontal method and rank structures. When A arises from the discretization of some PDEs and has a low-rank property (the intermediate dense matrices in the factorization have small off-diagonal numerical ranks), structured approximations of the d...
متن کاملIncorporating free-surface multiples in Marchenko imaging
Imagine placing a receiver at any location in the Earth and recording the response at that location to sources on the surface. In such a world, we could place receivers around our reservoir to better image the reservoir and understand its properties. Realistically, this is not a feasible approach for understanding the subsurface. Here, we present an alternative and realizable approach to obtain...
متن کاملSubsalt imaging with internal multiples
If singly scattered seismic waves illuminate the entirety of a subsurface structure of interest, standard methods can be applied to image it. In many cases, subsalt imaging for example, a combination of restricted acquisition geometry and imperfect velocity models results in regions of the model that are not illuminated with singly scattered waves. We present an approach to use multiply scatter...
متن کاملEstimating Imaging Artifacts Caused by Internal Multiples
Imaging with seismic data is typically carried out under the assumption of single scattering. Here we illustrate a theory that includes multiply scattered waves in the imaging process. We estimate artifacts in the image caused by internal multiples rather than estimating the multiples themselves in the data. The theory behind this approach comes from a series derived from the LippmannSchwinger ...
